WEV263B-030 is a 63A 30mA Type B RCD designed for applications where smooth DC residual currents and higher-frequency AC residual currents may be present. Suitable for EV charger installations, solar PV systems, UPS systems and frequency converters, it provides broader protection than conventional RCD types.
Rated at 63A, this RCD is the installer’s choice for larger EV charging points, heat pump consumer units, solar PV arrays, UPS setups, and industrial inverter systems. Fully compliant with IEC/EN 62423 and BS7671:2018+A2, it delivers reliable fault disconnection for demanding projects.
Installer Tip: Choose the 63A rating when circuit demand is higher than 40A or when multiple heavy-load devices (EV chargers, UPS, PV inverters) are connected on the same system.
